Re: [PHP-DB] Random - not that random

Hi Dan,

You need to call mt_srand() first to seed the random number generator. It's all 
described here:

[PHP-DB] Random - not that random

2001-05-17 Thread Dan Eskildsen 

Newbie alert

Hi!  Here is a piece of coding.  It randomly choose between four options to
display on my homepage.  The problem is that it doesn't seem to be that
random - rather biased.  The last option $message[3] is displayed 9 out of
10 times.  Any suggestions?



$message[0] = '
Rengøringsvogne, mopper m.m.';
$message[1] = '
Nilfisk Advance rengøringsmaskiner';
$message[2] = '
Har du set vores Vinduespudserstiger?';
$message[3] = '
Vi importerer selv vore polisher
fra en af Canadas førende Polishfabrikker.';

$number = mt_rand(0,3) ;
print"$message[$number]";
